Specification of Letters Patent.

Application filed September 24. 1908.

Be it known that I, Gnonon E. unnan,

a citizen of the United States, residing at Melvin, in the county of Ford and State of Illinois, have invented no i and useful linprovements in higon-Dumping i\pparatus, of which the following is a specilication,

reference being had to the accompanying drawings, forming a part thereof.

The purpose of this invention is to provide an apparatus by which a loaded wagon may be dumped by elevating bodily one end with the axle and wheels at that end so as to cause the load to be discharged by gravity from the other end of the wagon box.

It consists of the structure shown and described, as indicated in the claims.

In the drawings :Figure l is a plan view of the apparatus involving this invention. Fig. is a detail section at the line 2-2 on Fig. 1, with the addition of a. side elevation of the *agon in position on the device shown in full lines before elevating, and in dotted lines after elevating, the elevated wheels being broken away to disclose the lifting members. Fig. 3 is an end elevation of the structure shown in Fig.

1. Fig. 4 is a side elevation of the same. i

Fig. 5 is a detail section at the line 5 5 on Fig. 1.

The structure which embodied in this invention comprises a frame designed to be locally fixed in operation, but movable from location to location as required for use. Such frame consists of a horizmitally extended base rest ing on the ground, two rigid uprights spaced apart sullicicntl for a road way or wagon path between them; a wagonlift. consisting of a. frame adapted to seat the pair of wheels which are to be lifted, and lifting connections from the two end. of such wagon lift extending over guides at the top of the standartjls and thence down to a windlass shaft by which they are wound for lifting; shaft in opposite directions. and clutch connections for shifting the power from one train to the other for lifting or lowering, as required In connection with these principal elements the apparatus comprises dc vices for predeterniining the height of lift for shifting the clutch when the limit of lifting or lowering movement is reached.

The base frame comprises transverse sills, l, 1, connected by four longitudinal base the axle and hub of l Patented Jan. 25, 1910. Serial No. 454,600.

girders, comprising extreme girders, 2, 2, near the ends of the sills, and intermediate girders. i 2*. spaced apart the distance necessary for the wagon path. All of said girders are tied together by the transverse thresholds, 3, lodged above the girders and inclined in the longitudinal direction of the apparatus that is, transversely of said thresholds, oppositel v,both sloping down outwardly, proper slope being produced by bcvcling the ends of the girders to form the seats for the thrcslmldspas seen in Fig. 2. To these lixed thresholds. 3, 3, there ore hinged ft'llding thresholds, I), 3, of suitable width to extend in the longitudinal direction of the apparatus to the level of the lower surface of the base sills, 1, 1, so as to rest upon the ground or floor on which the latter may be supported. Upon each of the intermediate longitudinal girders, 2. there is erected an upright standard or post, 4, l'ootod on the girder and stayed by braces, extending in four directions to the fixed thresholds. I The lifting platform is a frame consisting of two transverse sills, t5, (3, crossed and connected by two longitudinal ties, T, T, lodged above the end portions of the sills and lirnilv bolted thereto. This frame is lno]un'tioncd as to its longitudinal dimension so that it will enter between the proximate edges of the fixed sills, 3, l, and as to its transverse dimension so that it will enter between the uprights, 4, 4. when the longitudinal ties, T, T, are notched at the middle point of their lcn 'lh to engage the posts as seen in l io'. l. .\t each end of the lifting platform it is prt'lvided with a. lifting bail, 5'', formed of suitably heavy rod folded t form an eve or loop, H. from which two trains for rotating the windlass arms diverge downwardly and are bent parullcl at their lower ends to pass through the longitndimtl tics, T, and transverse sills. 6. below which the rods are threaded to receive nuts. S, which allord them engagement below the sills, 6. Two guide plates are providcd for engaging the posts, one the plate. El, which is bolted upon the upper surface of the ltu'igittnlil'ial tic, T. bounding the mar-- gin of the notch in the tie which accommodates the post, the other comprising two parts. and ti which are adapted to engage between them the loop, 8, of the bail, onto which the) arc clamped by the bolt, 10. the member, 10, being bifurcated to engage or clasp one side of the post.
